The 16 mm is Harken'sŪ smallest block. It is perfect for small synthetic control lines found on high-tech dinghies.
The patented bearing system uses stainless steel balls in a captive grooved race and has a 250 lb (113 kg) safe working load - the highest on the market compared to similarly sized blocks.
The 404 uses an O-ring to keep the line in the sheave during intermittent loading.
